Another Fischer achievement was the synthesis of small peptides via the condensation of amino acids. Fischer suggested that there was a common linkage that held pairs of amino acids together in all proteins—the peptide bond. He understood that proteins were tremendously complex, owing to the large number of constituents and the fact of stereoisomerism. By 1916 Fischer had synthesized and characterized 100 peptides, but knew they represented a tiny fraction of what was possible, see also Amino Acid Carbohydrates Isomerism van t Hoff, Jacobus. 

Oddly enongh, van t Hoff, with whom Le Bel had worked in Wnrtz s laboratory shortly beforehand, independently arrived at the same theory from a different starting point at virtnally the same time, see also Chirality Pasteur, Louis van t Hoff, Jacobus. 

The electronic and molecular geometries of covalent molecules, and hence their resulting polarities, can thus be predicted fairly accurately. Armed with these tools, one can predict whether or not a molecule should be soluble, reactive, or even toxic, see also Bonding Avogadro, Amedeo Bohr, Niels Cannizzaro, Stanislao Dalton, John Le Bel, Joseph-Achille Lewis, Gilbert N. Lewis Structures Pauling, Linus Thomson, Joseph John van t Hoff, Jacobus.
